Male genitalia figured from cotype in National Collection. 



Specimens from Doctor Barnes' material in the National Collec- 

 tion and Collection Barnes I have also identified as this species. 

 They are a trifle larger and the male genitalia are also somewhat 

 larger. They may prove to be a different but very close species. 

 For the present I am inclined to regard them as only a variety or 

 race; collected at Vineyard, Utah ("Aug., 1912") by Tom Spalding. 

 This species is chiefly distinguished from em^aciatana and those that 

 immediately follow it in this arrangement by the termen of the fore 

 wing, which in larana is almost vertical rather than decidedly 

 slanting, 



Kearfott's specimens in the American Museum were not correctly 

 determined. 



Alar expanse — 19-24 mm. 



Type. — In British Museum.

71. EUCOSMA EXCLUSORIANA, new species. 



(Fig. 160.) 



Sordid whitish overlaid with ochreous and ashy fuscous scales. 

 Palpi white dusted with fuscous. Face clear white. Head yel- 

 lowish. Fore wing with termen somewhat slanting, slightly con- 

 cave; veins 3, 4 and 5 approximate at termen; in general appear- 

 ance yellowish white, spotted and marked with ashy fuscous; the 

 fuscous dustings forming a distinct spot in cell near base (indi- 

 cating a basal patch in part), at end of cell a larger, more con- 

 spicuous spot, another in apical area over ocellus and a small tri- 

 angular spot or dorsum before tornus, the latter rather obscure; 

 costa strigulated with white and fuscous; two black streaks in 

 ocellus; cilia heavily dusted with blackish fuscous. Hind wing 

 pale, smoky fuscous, somewhat darker along outer margin; cilia 

 white with a fuscous basal line. Legs white, dusted on outer sides
